  • I don’t believe that because this isn’t about capacity calibration, but more so that the battery voltage is almost constant between about 20% and 90%, though varies by battery type, and no matter what, the controller can’t exactly know how much the battery is actually charging and discharging so it has to guess the current state. I’ve seen this happen on a Dell XPS laptop I have from work, I manually set it to limit charging to 80% since the built in “Primarily AC Use” mode cycles it around 95%, and it doesn’t do the occasional recharge to 100% by itself, so about once a month it would jump from whatever percentage it was at to 7%, even from 80%.








  • Alec in his own video mentions that the issue isn’t that the Americium decays, but that the electronics themselves age and fail, which applies to both the ionization detectors and photoelectric detectors.

    This is one of the things you just don’t wanna mess with, as such a failure is completely unpredictable, and from what I know some manufacturers are even beginning to make detector units with non-replaceable batteries, intended to be replaced whole when the battery dies after years of runtime, to make it impossible to keep using a detector after its rated lifetime.
